Start with .github/workflows/mcp-registry.yml and inspect the linked GitHub Actions run to trace where the deprecated schema error occurs. Determine which registry validation or publishing behavior rejects the 2025-12-11 schema, then verify that a newer Context7 MCP server can publish successfully without the error.
